The W11422743 is the OEM Whirlpool refrigerator compressor — the heart of your refrigerator's sealed cooling system. The compressor pressurizes refrigerant and circulates it through the condenser and evaporator coils to maintain cold temperatures. When the compressor fails, the refrigerator loses all cooling ability. This is a genuine OEM part engineered to Whirlpool's original specifications for a guaranteed fit and full cooling performance restoration.
